Title:
LIFTING STRUCTURE FOR SMOKE EXHAUST HOOD
Document Type and Number:
Japanese Patent JP2017067424
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a lifting structure for a smoke exhaust hood which facilitates a manual lifting operation and improves user friendliness and durability.SOLUTION: In the smoke exhaust hood, a lifting cylinder is inserted into a suspension fixing cylinder in a slidable manner and can be fixed at any position. In the smoke exhaust hood, a magnet part 5 provided in the suspension fixing cylinder 2 and a magnet slide rail 7 provided in the lifting cylinder 3 are attracted and in a state where the magnet part 5 and the magnet slide rail 7 are attracted, the lifting cylinder is slid and moved, such that the lifting cylinder is freely lifted and fixed at any position. The smoke exhaust hood utilizes properties of a magnet that, when pulling the magnet in a vertical direction with respect to an attraction face, a large force is required but when moving the magnet in parallel with the attraction face (sliding and moving the magnet), a small force is enough therefor.SELECTED DRAWING: Figure 3
